And just to confuse us a little more, Billi was then snapped without the ring - of course, she may have taken it off for a walk along the beach, who can tell.

The newly tanned and really happy pair have posed up a storm on the beach, by the bar and in their bedroom this week, and Billie couldn't resist showing off her amazing body.

Glowing in love?

Wearing a bright green bikini, the Bikram Yoga instructor relaxed with a drink and flaunted her cleavage for all it's worth, before going on a bike ride in a matching playsuit.

All that hard work meant they needed a break later one, and enjoyed a romantic candle-lit evening together before retiring into their room - where the bed had been covered in rose petals in the shape of a heart.

Now if that isn't suspicious, we don't know what is.

Could there be wedding bells sounding for the loved-up couple?

When 3am contacted Billi's reps, they replied with "no comment".

Take a trip through their wonderful holiday and get just as jealous as us, in the gallery at the top.
